windows 中 hadoop2.7.5 在eclipse上的插件编译

1、下载插件源码
https://github.com/winghc/hadoop2x-eclipse-plugin
2、下载ant1.10.1
http://mirrors.tuna.tsinghua.edu.cn/apache//ant/binaries/apache-ant-1.10.1-bin.tar.gz
3、配置ant环境变量

ANT_HOME

E:\apache-ant-1.10.1-bin\apache-ant-1.10.1

path：增加%ANT_HOME%\bin

%JAVA_HOME%\bin;%M2_HOME%\bin;%ANT_HOME%\bin;----

4、下载hadoop-2.7.5和hadoop2x-eclipse-plugin插件，解压

5、配置编译插件

 进入到hadoop2x-eclipse-plugin-master\src\contrib\eclipse-plugin\build.xml文件中，找到

<target
name="jar" depends="compile" unless="skip.contrib">这一行

往下找

 <copy
file="${hadoop.home}/share/hadoop/common/lib/htrace-core-${htrace.version}.jar"  todir="${build.dir}/lib" verbose="true"/>

修改为

 <copy
file="${hadoop.home}/share/hadoop/common/lib/htrace-core-${htrace.version}-incubating.jar"  todir="${build.dir}/lib" verbose="true"/>

然后在此之后再增加以下两行

<copy
file="${hadoop.home}/share/hadoop/common/lib/servlet-api-${servlet-api.version}.jar"  todir="${build.dir}/lib" verbose="true"/>

 <copy file="${hadoop.home}/share/hadoop/common/lib/commons-io-${commons-io.version}.jar"  todir="${build.dir}/lib" verbose="true"/>

然后再找到

<jar

      jarfile="${build.dir}/hadoop-${name}-${hadoop.version}.jar"

      manifest="${root}/META-INF/MANIFEST.MF">

 
    <manifest>

   <attribute name="Bundle-ClassPath" 

    value="classes/, ------------这一行

追加以下两行

 lib/servlet-api-${servlet-api.version}.jar,

 lib/commons-io-${commons-io.version}.jar,

并将lib/htrace-core-${htrace.version}.jar

替换为lib/htrace-core-${htrace.version}-incubating.jar

6、hadoop2x-eclipse-plugin-master\src\ivy\libraries.properties文件中，更改下列属性和其值使其对应hadoop2.7.5和当前环境的jar包版本，按以下配置文件中的版本好：
     hadoop.version=2.7.2       ------Hadoop版本号
     apacheant.version=1.10.1   -------ant版本号
     commons-collections.version=3.2.2
     commons-httpclient.version=3.1
     commons-logging.version=1.1.3
     commons-io.version=2.4
     slf4j-api.version=1.7.10
     slf4j-log4j12.version=1.7.10
7. hadoop2x-eclipse-plugin-master\ivy\libraries.properties文件中，属性和值的修改同上面的2.。另外需要增加一个修改：
     htrace.version=3.1.0

8、然后执行

ant
jar -Dversion=2.7.5 -Declipse.home=D:\eclipseOXY\eclipse-jee-oxygen-R-win32-x86_64\eclipse -Dhadoop.home=E:\Hadoop\hadoop-2.7.5

-Declipse.home是eclipse路径

-Dhadoop.home是Hadoop所在路径

如果遇到ivy-resolve-common:位置会有短暂的停顿，等待即可。一般不会超过2分钟，如果时间太长，中断操作，然后检查配置文件是否出错

正常编译通过如下：

check-contrib:

init:

     [echo] contrib: eclipse-plugin

init-contrib:

ivy-probe-antlib:

ivy-init-antlib:

ivy-init:

BUILD SUCCESSFUL
Total time: 31 seconds

会出现以下警告 [javac]
E:\Hadoop\hadoop2x-eclipse-plugin-master\src\contrib\eclipse-plugin\build.xml:76: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds，上方的日志

解决方案：

 
<javac

     encoding="${build.encoding}"

     srcdir="${src.dir}"

     includes="**/*.java"

     destdir="${build.classes}"

     debug="${javac.debug}"

     deprecation="${javac.deprecation}"  
includeantruntime="on">  增加此字段即可，重新编译

     <classpath refid="classpath"/>

    </javac>

解决  <javac

     encoding="${build.encoding}"

     srcdir="${src.dir}"

     includes="**/*.java"

     destdir="${build.classes}"

     debug="${javac.debug}"

     deprecation="${javac.deprecation}"  
includeantruntime="on">

     <classpath refid="classpath"/>

    </javac>
